📄 Description

Overview

Add langchain-mineru integration docs.

langchain-mineru is a LangChain document loader powered by MinerU. It converts documents into LangChain-compatible Document objects in Markdown format, supports both local file paths and URLs, provides flash and precision modes, and optionally supports split_pages for PDF inputs. The integration is intended for downstream LangChain workflows such as text splitting, embedding, and retrieval.

Additional notes

This PR adds documentation for the official langchain-mineru integration.
The docs cover:

  • installation and import
  • quick start usage
  • local file path and URL inputs
  • flash mode (token-free) and precision mode (token required)
  • optional split_pages support for PDFs
  • multi-source loading
  • example RAG pipeline usage
  • key parameters, metadata, supported formats, and limitations

The integration returns Markdown-based LangChain Document objects and is designed to work smoothly with downstream LangChain components.
